This is the 8th WHO annual report on global tuberculosis control. It includes data on case notifications and treatment outcomes from the 201 national TB control programmes (NTPs) that reported to WHO for 2002, together with an analysis of plans, budgets, expenditures, and constraints on DOTS expansion for 22 high-burden countries (HBCs). Nine consecutive years of data are used to assess progress towards the 2005 global targets for case detection (70%) and treatment success (85%).
